BACKGROUND A few reports confirm the ability of Helicobacter pylori to form biofilm. However, conclusive data do not exist concerning the factors that favor this ability. OBJECTIVES Evaluation of the factors associated with the biofilm formation ability of H. pylori including bacterial, physical and chemical, and environmental factors was the research's(More)
Treatment success of H. pylori eradication therapy has declined worldwide largely because of increased antimicrobial resistance. New therapeutic approaches are needed, especially for countries like Iran, where resistance to commonly used drugs is already widespread and traditional H. pylori therapies produce poor cure rates. To review the results of(More)
BACKGROUND During the last decades the rate of multidrug resistance among clinical Helicobacter pylori isolates has increased. Active pumping out of the drugs may be an important mechanism for multidrug resistance in H. pylori strains. OBJECTIVES The aim of this study was to evaluate the association of two H. pylori efflux-genes, hp1181 and hp1184 with(More)
BACKGROUND/AIM Despite the significant number of studies on H. pylori pathogenesis, not much data has been published concerning its ability to form biofilm in the host stomach. This study aims to evaluate the potential of clinical isolates of H. pylori to form biofilm in C57BL/6J mice model. MATERIALS AND METHODS Two strains of H. pylori were selected(More)
AIM To evaluate the role of biofilm formation on the resistance of Helicobacter pylori (H. pylori) to commonly prescribed antibiotics, the expression rates of resistance genes in biofilm-forming and planktonic cells were compared. METHODS A collection of 33 H. pylori isolates from children and adult patients with chronic infection were taken for the(More)
